Description

Technical Field

[0001] This utility model relates to the field of experimental instrument technology, and in particular to a device for fixing and stacking culture dishes. Background Technology

[0002] In microbiology laboratories, multiple petri dishes are often handled, especially during inoculation in biosafety cabinets. When dealing with large batches of specimens, the petri dishes are stacked. However, since the petri dishes are not specifically designed for stacking and different sizes of petri dishes are difficult to stack, they are prone to tipping over during stacking or transportation. This makes transportation inconvenient, easily leads to contamination or sample redoing, and wastes time and materials. Furthermore, direct contact between the petri dishes increases the probability of contamination. To address the above shortcomings, this application is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a device for fixing stacked culture dishes, which solves the problems of easy tipping over during the stacking and transportation of culture dishes and the increased probability of contamination caused by direct contact between stacked culture dishes.

[0004] To address the aforementioned problems, this utility model provides a petri dish stacking and fixing device, comprising a cylindrical body, which has a top, a bottom, a placement cavity, and a sliding door. The placement cavity can be of any shape, such as square or circular, preferably circular. The placement cavity is used to place petri dishes. The sliding door is movably installed, and the placement cavity can be opened and closed by moving the sliding door. When the sliding door is opened, the petri dish can be placed into the placement cavity. The sliding door has an arc-shaped structure and rotates around the axis of the cylindrical body when moving, so that it does not occupy external space when opened, facilitating operation in small spaces. A connecting structure is provided on the top, and a mating structure is provided on the bottom. When stacked, the connecting structure of adjacent cylindrical bodies can cooperate and connect with the mating structure to achieve stable stacking, facilitate transportation, and prevent tipping.

[0005] According to one embodiment of the present invention, the placement cavity is provided with a clamping body and an elastic body. The clamping body is used to clamp the culture dish, and the elastic body is made of a spring or an elastic material.

[0006] According to one embodiment of the present invention, the clamping bodies are provided in two sets and are arranged symmetrically to facilitate a stable clamping effect.

[0007] According to one embodiment of the present invention, the clamping body is made of an elastic material and is configured as an arc-shaped structure to match the outer circle of the culture dish, thereby further stabilizing the clamping.

[0008] According to one embodiment of the present invention, the side of the clamping body that is in contact with the culture dish is provided with several anti-slip protrusions.

[0009] Optionally, the connection structure and mating structure can be a snap-fit, plug-in, threaded connection, or other similar method.

[0010] Preferably, the connecting structure includes a protrusion, and the mating structure includes a groove that mates with the protrusion, thus achieving a concave-convex mating connection.

[0011] According to one embodiment of the present invention, the connecting structure includes a magnetic body, and the mating structure has a ferromagnetic part, which is fixed by magnetic connection.

[0012] According to one embodiment of the present invention, there is a semi-circular inner ring between the top and the bottom. The sliding door, the top, the bottom and the inner ring together form a placement cavity. When the sliding door is in motion, it moves around the inner ring.

[0013] According to one embodiment of the present invention, the top, bottom or inner circumference is provided with a slide rail that cooperates with the sliding door, so that the sliding door can move smoothly and steadily.

[0014] According to one embodiment of the present invention, the inner circumference and / or sliding door are made of transparent material to facilitate observation of the internal culture dish.

[0015] The beneficial effects of this utility model are that the petri dish stacking and fixing device can accommodate and stack petri dishes of various sizes. During the stacking process, adjacent devices are fixed through connecting and cooperating structures, which can effectively prevent tipping and contamination. It facilitates the batch transfer of petri dishes. Furthermore, the structural shape of this device and the rotating opening method of the sliding door make the space required for its use small, enabling large-scale operation in narrow spaces, making it more convenient to use.

The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0024] Example 1:

[0025] A device for fixing stacked petri dishes, such as Figure 1 The device includes a cylindrical body 100 with a circular outline. It has a top 2, a bottom 6, a placement cavity 7, an inner circumference 4, and a sliding door 1. In this embodiment, the placement cavity 7 is circular, but other shapes can be selected in other embodiments. The inner circumference 4 is semi-circular and is fixed between the top 2 and the bottom 6. The sliding door 1 is an arc with a diameter larger than that of the inner circumference 4. The sliding door 1, the top 2, the bottom 6, and the inner circumference 4 together form the placement cavity 7. When the sliding door 1 moves, it moves around the inner circumference 4.

[0026] The placement chamber 7 is used to place culture dishes. The opening and closing of the placement chamber 7 is achieved by moving the sliding door 1. After the sliding door 1 is opened, the culture dishes can be placed into the placement chamber 7. Since the sliding door 1 has an arc-shaped structure, it rotates around the axis of the cylindrical body 100 or the center of its cross-section when it moves, so that it does not occupy external space when it is opened, which facilitates large-scale operations in small spaces (such as biosafety cabinets).

[0027] Both the inner circumference ring 4 and the sliding door 1 are made of transparent material, such as transparent plastic, to facilitate observation of the internal petri dishes.

[0028] A connecting structure 21 is provided on the top 2, and a mating structure 61 is provided on the bottom 6. When stacked, such as Figure 5 , Figure 6 The connecting structure 21 of adjacent cylindrical bodies 100 can cooperate and connect with the mating structure 61 to achieve stable stacking, facilitate transportation and prevent tipping.

[0029] Optionally, the connecting structure 21 and the mating structure 61 can be connected by snap-fit, plug-in, threaded connection, etc. In this embodiment, a plug-in mating is adopted. Specifically, the connecting structure 21 includes a disc-shaped protrusion, and the mating structure 61 includes a groove that mates with the protrusion. The two achieve a concave-convex mating connection. The connecting structure 21 includes a magnetic body. The protrusion can be entirely or partially set as a magnet. The groove of the mating structure 61 is partially or entirely provided with a ferromagnetic part. The two are fixed by magnetic connection, which facilitates the fixing and disassembly of stacked structures.

[0030] Example 2:

[0031] Based on Example 1, such as Figure 3 The placement cavity 7 is equipped with a clamping body 3 and an elastic body 5. The clamping body 3 is used to clamp the culture dish, and the elastic body 5 is made of spring or elastic material.

[0032] Two sets of clamping bodies 3 are provided and symmetrically arranged to facilitate a stable clamping effect. They are made of elastic materials, such as rubber or silicone, and are designed with an arc-shaped structure to match the outer circle of the culture dish, further stabilizing the clamping. The side of the clamping body 3 that contacts the culture dish is provided with several anti-slip protrusions 31 to prevent the culture dish from sliding or rotating.

[0033] Optionally, the top 2, bottom 6, or inner ring 4 are provided with slide rails that cooperate with the sliding door 1, serving as tracks for the sliding door 1 to move smoothly and steadily, and also acting as guides.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
